international customers due to their durability and various other attributes.

Specifications of Tool Steel Bar:

Heat Treatment:

Normalizing:

Normalizing temperature: 860-900oC.

Soft Annealing:

Heat to 760-800oC, cool slowly in furnace

This will produce a maximum Brinell hardness of 217

Stress Relieving:

Stress relieving should be carried out in order to remove machining

stresses by heating to approx. 650oC, holding for 1-2 hours at heat,

and allowing air cooling. This operation is performed to reduce distortion

during heat treatment.

Hardening:

Harden from a temperature of 830-890oC followed by oil quenching

Hardness after quenching is approx. 64 HRC

Tempering:

Tempering temperature: 150-180o C

Manufacturing of Tool Steel Bar

a) Cold rolling, slitting, and edge processing

b) Heat treatment: annealing, tempering, hardening

c) Cold finishing and polishing

Packaging of Tool Steel Bars:

Shanghai Metal Products are packed and labeled according to regulations and customer requests. Great care is taken to avoid any damage which might be caused during storage or transportation. In addition, clear labels are tagged on the outside of the packages for easy identification of product and quality information.
